I saw those as well, the Bonhams one someone made a great score.
The second one is badly corroded, last kanji is hardly readable so they made a guess i think, but to me should be the late Edo Tomohisa (same as the published one in my article)
Thank you Dale, i actually know those but i deliberately excluded cause not signed.
Actually i have other signed examples but since the workmanship and subject are the same i thought no need to include those.
Recently i made a research on the subject depicted on the following tsuba made by Yaji Tomoyuki (八道友之) that i currently own, since i thought it was quite interesting what i found i made an article about it.
Feel free to download it and i'd be happy to hear your thoughts about it.

I do use Wise, very convenient and fast also to transfer money to Japan.
A suggestion when sending money to Japan, ask for kanji/katakana account name or it can cause problems for transfer.
i leave you my link so you can have a free transfer up to 500€ (and i can get some cashback )

looks like 需應佐々木重輔
which should mean "on request of Sasaki Shigesuke (or Jusuke)"
Seems he liked his swords being custom made
